To all whom it may concemc w Be it known that I, GEQRGE H. AUGHEN-BAUGH, a citizen of the United States, residing at York, in the countyof York and State of Pcmosylvsn'is, have invented oer-- tcin new anduseful Improvemshts in Com? prcssion Stop and Waste Cocks; and 1. dodeclare the folloyvin to he a full clear, and exact clescription' o theinvention, such as will enable others 'sl?;i1led in the art to which isappevtains to mshs'cnki the same.

This invention ielates to water distribution, and more csue cially to(30638 and faucets of valves; and t 'e object of the same is to produce'cni'mproved device of this character which can he used as a compressionstop and Waste cock or simply as a compression cock at will. Thisohjectis carried out by providing the valve stem Withc waste vent ind a needlevalve for closing it when desired, and by constructing the entire devicein the manner hereinafter more fully (lescribcd nd claimed and as shownin the drcwino's Whcrcm p Flgiue 1 1s a central VGIolCfil sectional viewthrough this device with the main valvc closed and the waste valveopened. 2 is a cross section oh the line 2-2 of Fig. 1. Fig. 3 is atransverse section on the line 33 of Fig. l with the main valve open andthe Waste valve closed.

In the drawings is shown an embodiment of this device when used as avalve Whose casing G forms communication between the inlet pipe 1' andthe outlet pipe although it will be clear that the pipe 1 shown hereincould he the inner or threaded end of a carrying a seat for the mainvalve V spigot and the pipe 0 its outlet and or nozzle Without departingfrom the spirit ofthe invention. Said casing contains a loridse B whichtravels to and from its seat on threads '1" within the casing and aroundthe valve, and is moved by means of a stem Shaving a handle H at itsouter end as usual. No novcity is claimed for the features thus fardescribed, nor on the Washer W on the end of the main valve which seatsagainst a ridge R around the opening through ,ths bridge B when thisvalve is closed, as this form. of

. compression cock is Well known to the trade Qomins now moreparticularly to the deilfifllsfif the present invention, the threads 1are by piefeicnce mutilated as seen at 1 in 'F1gs. 2 and. 3 so as topermit the fluid passlugthrough ths velve casing and entering the space2 behind the main valve V when the latter is cpcn, to iicw through saidnub tilaticns 1 into ths space 3 behind "the threaded portion of thisvalve, whence it can not escape because of the packing c and gland nut 5which are employed as usual and fit closely around the stem S. But saidstem thc'prcsent instance is made tubular,. its fine small longitudinalborc 6 communicating with a cross port 7 near its juncture with the head10 of the main valve Y, and lcscliiig thence outward to the extericicside of the packing 4 and the gland nut 5 to c lateral outlet port 8;and when the valve stands slightly open or when the main valve "J at allraised from its 5 R the iiuid wl c n the space 2 {if under rs sure) passthrough the mutilstio into the cross port 7, along the bore 6, and outthe outlet port 8. G11 the other hand, when the main valve V is screwedhomeso that it closes against its sect R, none of the fluid in the pipeI on the inlet side of the casing C cah escape through the outlet port8, but the fluid in the pipe 0 if subjected to back pressure set backthrough the space 2 and along the course outlined and run out the outletport 8. The device thus vccomes :1 compression stop and waste.

At the hack of the main valve head 10 is formed an annular ridge llcapable of be" ing seated against a Washer 12 which rests against theinner end of the packing i, and. when stem is unscrewed so that the mainvalve is dmwn outwsvd to the extent shown hi 3, the spaceB whichnormally coramunicstes with the cross port 7 is thus closed and no wastewill escape from the interior of the casing or from either pipe or (1 YA means for converting this device into an ordinary cock is to close thebore 6. This by preference I accomplish in the follow' manner: At thejuncture of said horc W the. outlet port 8, the "former is enlarged soas to produce a valve seat 13, and adapted to close against the same isthe conical or needle and of a. supplemental or Waste valve Whose stem15 in the present instance has threads engaging female threads 17 Withinthe enlarged portion 18 of the bore 6 as showm thc'cuter end of saidstsmpsssing through, a packing l9 and a suitable gland nut 2C- andhaving knurled head 21 at its szztremity as shown. Wh m now this head isturned in at PE'OilQK direciicu to its ill) Heat the stem 1.5 andwithdrew 'iihe valve from the seat 13, the Waste passage epen dis seenIn i lg. l; but when the head is turned in the other direction and the"tem forced inward, the valve 1 ieieses against the seat as seen in Fig.3 am]. thereiifere he waste passing threugh the here 6 can cape.

l (i() net wish in be limited to the precise eens'hrnetii'in of the 521imflemenml valve here in shown, but find that such is a convenientarrangement. because the kniifleil 11PM]. 31 stands at the center ef thehandle 1? min readily accessible t0 the operate".
